Relative to bacteria, from Wikipedia: There are two main types of bacterial cell walls, Gram positive and Gram negative, which are differentiated by their Gram staining characteristics.
Gram positive: Teichoic acids give the Gram positive cell wall an overall negative charge due to the presence of phosphodiester bonds between teichoic acid monomers. Gram negative: In addition to the peptidoglycan layer, the Gram negative cell wall also contains an additional outer membrane composed by phospholipids and lipopolysaccharides which face into the external environment. As the lipopolysaccharides are highly-charged, the Gram negative cell wall has an overall negative charge. >From what I have read, viruses have a slight negative charge at neutral PH. - Steve N ________________________________ From: Bethany Methven [mailto:mrs_ak_h...@yahoo.com] Sent: Wednesday, October 29, 2008 12:38 AM To: silver-list@eskimo.com Subject: CS>positive silver ions and negatively charged bacteria Hi, I'm new to this list. Here in Alaska, very few people actually know about CS. I am trying to learn as much as I can so that I can educate those around me. I have been studying about the positive charge from silver ions losing an electron during the electro colloidal process. Anyway, my question is - Does anyone know if all bacteria, fungus, viruses, etc are negatively charged? Some web site was talking about how the positive charge from the silver ions attracts to the negative charge of the bacteria, and then basically short circuits it's biological clock, making it unable to reproduce. If this is true, then how effective are silver particles, if they are negatively charged, vs. the positive charge of the ions? I have heard so much confusion regarding ions vs. particles. I"d like to hear some other opinions. Thanks - Beth
